Help! Am I doing something wrong!?

[Kyla Smith]

Can someone help me please. The past 2 times Ive tried to hatch the 44 eggs I only have gotten 9 the first time and 10 this time. Am I doing something wrong to make the other not hatch? I am watching the temp and humidity (100.0 and 70%) I don't open to get the hatched chicks out if there are any pipped. I just don't understand what I am doing wrong!!

Are you maintaining that temperature and humidity level the entire time you are incubating? What type of incubator are you using? Are you using an automatic turner or turning manually? Do you candle at different points of incubation and, if so, at what point are you finding that development stops in those eggs that do not hatch? Have you done any egg-topsides on the failed eggs and, if so, what did you find? Have any of the eggs that don't complete hatching pipped and then failed or are they not pipping (internally or externally) at all?
